This camera area often features a decorative ring (CAM Deco) protruding from the surface of the battery cover, and the camera module's protective cover is usually secured to the battery cover via this decorative ring. However, current smartphone and other electronic device battery covers are usually opaque, making the area corresponding to the camera module easily scratched and abraded due to its lower hardness. Furthermore, the decorative ring on the battery cover increases its structural complexity, affecting its appearance and overall aesthetics. Utility Model Content

[0031] Please see Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a schematic diagram of the structure of an electronic device disclosed in an embodiment of this application. Figure 2for Figure 1 A schematic diagram of the electronic device from another perspective. Figure 3 for Figure 1 A schematic diagram of the internal structure of the electronic device shown. Figure 1 , Figure 2 and Figure 3 As shown, the electronic device 1 provided in this application embodiment may include, but is not limited to, smartphones, tablets, handheld computers, handheld game consoles, personal digital assistants (PDAs), portable media players (PMPs), navigation devices, wearable devices, smart bracelets, pedometers, displays, and other mobile terminals.

[0032] For ease of description, the specific structure of the electronic device 1 provided in this application will be further illustrated below using a smartphone as an example.

[0033] The electronic device 1 provided in this application embodiment includes a mid-frame 10, a main display module 20, an optical module, and a housing assembly 60. The mid-frame 10 serves to position, support, and protect the main display module 20, the optical module, and the housing assembly 60. The main display module 20 and the housing assembly 60 are located on opposite sides of the mid-frame 10 and are fixedly connected to the mid-frame 10. Specifically, the main display module 20 and the housing assembly 60 can be fixedly connected to the mid-frame 10 by a dispensing process to improve the reliability and stability of the connection. The mid-frame 10, the main display module 20, and the optical module constitute the body of the electronic device, and the housing assembly 60 is applied to the rear of the electronic device body.

[0034] In this embodiment, the main display module 20 and the housing assembly 60 are respectively fixedly connected to opposite sides of the middle frame 10. The main display module 20, the housing assembly 60, and the middle frame 10 together form an installation space, which is used to accommodate and install electronic components such as the battery module, optical module, and circuit board of the electronic device 1. Specifically, a first installation space can be formed between the middle frame 10 and the housing assembly 60, and at least some of the aforementioned electronic components can be disposed within the first installation space. A second installation space can be formed between the middle frame 10 and the main display module 20, and some of the aforementioned electronic components can be disposed within the second installation space. It is understood that the battery module can provide power to the main display module 20, the optical module, etc.

[0035] The middle frame 10 may include a border 11, which may be made of materials such as aluminum alloy, magnesium alloy, stainless steel, ceramic, glass, or plastic, but is not limited to these. Function buttons such as volume buttons and a screen-off button may be disposed on the border 11, and these function buttons are electrically connected to the processor of the electronic device 1. In an exemplary embodiment, the border 11 may be manufactured by at least one of the following methods: injection molding, compression molding, extrusion, forging, die casting, and computer numerical control (CNC) machine tool processing.

[0036] In this embodiment, the frame 11 may be made wholly or partially of a transparent material (not limited to glass, transparent plastic, etc.). By making the frame 11 of a transparent material, not only is processing and manufacturing easier, but the electronic components inside the electronic device 1 can also be visualized.

[0037] The main display module 20 has display and touch functions, meaning that the electronic device 1 can be operated by clicking on the main display module 20. The main display module 20 may include structural layers such as a touch screen, a light-emitting layer, a backplane layer, and a substrate layer, the specific structure of which can be selected according to different products. In this embodiment, the main display module 20 can be a Liquid Crystal Display (LCD), an Organic Light-Emitting Diode (OLED) display, an Active Matrix Organic Light-Emitting Diode (AMOLED) display, a Flexible Light-Emitting Diode (FLED) display, or a Quantum Dot Light-Emitting Diode (QLED) display, etc. The main display module 20 can be used to display image information and provide an interactive interface for the user.

[0038] In this embodiment, the optical module may include an input optical module 40 and / or an output optical module 50. The input optical module 40 may be a camera module, and the output optical module 50 may be a flash, an LED, or a dot matrix screen formed by an array of LED beads. The dot matrix screen can be used to display functional image information to the user. The functional image information includes, but is not limited to, displaying time, date, preset patterns, logos, etc., to increase the functional diversity, aesthetics, and personalized design of the electronic device 1.

[0039] In this embodiment, the electronic device 1 may further include a circuit board 30, which is located within the mounting space and fixed to the middle frame 10. The circuit board 30 is electrically connected to the battery, the main display module 20, the light-incident optical module 40, and the light-exiting optical module 50, respectively. The circuit board 30 may also integrate electronic components such as the processor, storage unit, baseband chip, and power management unit of the electronic device 1. The processor can control the display of the main display module 20 and the light-exiting optical module 50, as well as the imaging of the light-incident optical module 40. The circuit board 30 may be a printed circuit board (PCB), consisting of an insulating base plate, connecting wires, and pads for assembling and soldering electronic components, serving the dual function of conductive lines and an insulating base plate. The circuit board may be a single-sided board, a double-sided board, or a multi-layer board, which can replace complex wiring, enabling wiring and electrical connections or electrical insulation between various electronic components, and providing the required electrical characteristics.

[0040] In this embodiment, the electronic device 1 may further include at least one pressure-sensitive button 70, which is disposed on the housing assembly 60 and near the edge of the housing assembly 60. The pressure-sensitive button 70 is electrically connected to the circuit board 30 and the light-emitting optical module 50, and can control the light-emitting optical module 50 to display corresponding image information. For example, it can control the light-emitting optical module 50 to light up the screen; or, for example, pressing and holding the pressure-sensitive button 70 can turn off the screen of the light-emitting optical module 50; double-clicking the pressure-sensitive button 70 can adjust the display brightness of the light-emitting optical module 50 or change the display pattern. It is understood that the way the pressure-sensitive button 70 controls the light-emitting optical module 50 can be adjusted and preset according to specific needs, and this application does not specifically limit this.

[0041] Please refer to the following: Figure 4 and Figure 5 , Figure 4 This is a schematic diagram of the structure of a housing assembly disclosed in an embodiment of this application. Figure 5 for Figure 4 A structural schematic diagram of the housing assembly from another perspective. (See diagram below.) Figure 4 and Figure 5 As shown, the housing assembly 60 provided in this application embodiment is disposed on the back of the electronic device body having the middle frame 10, and includes a housing body 61 with at least a partially transparent design. The housing body 61 is disposed opposite to the main display module 20 and is detachably mounted on one side of the middle frame 10.

[0042] The housing body 61 is at least partially a light-transmitting area 613, which overlaps at least with the orthographic projection of the optical module of the electronic device 1 in the direction of the middle frame 10. The optical module includes an incident optical module 40 and / or an exit optical module 50. The light-transmitting area 613 is used for the light emitted by the exit optical module 50 to pass through, and / or for the light to pass through the housing body 61 and be received by the incident optical module 40.

[0043] In this embodiment, the light-transmitting area 613 includes a first surface 611 disposed opposite to the electronic device body and a second surface 612 disposed close to the electronic device body. The first surface 611 is provided with a protective layer, which corresponds at least to the optical module, and the Mohs hardness of the protective layer is greater than that of the housing body 61. The first surface 611 is the outer surface of the housing body 61, and the second surface 612 is the inner surface of the housing body 61, facing the interior of the electronic device 1.

[0044] In this embodiment, the pressure-sensitive button 70 is disposed on the first surface 611 (i.e., the outer surface) of the housing body 61, and an opaque adhesive patch area is formed on the first surface 611. The user can input the pressure-sensitive button 70 by pressing the opaque adhesive patch area.

[0045] It is understandable that, in order to prevent accidental operation when the electronic device 1 is grasped, the pressure-sensitive button 70 is located on the first surface 611 of the housing body 61 near the edge.

[0046] In this embodiment of the application, the housing body 61 may be the entire back cover of the electronic device 1 made of a transparent material (such as glass, transparent plastic, etc.).

[0047] In one embodiment of this application, the housing body 61 and the frame 11 may be made entirely or partially of transparent materials (such as glass, transparent plastic, etc.). This not only facilitates processing and manufacturing, but also allows at least some electronic components of the electronic device 1, such as the light-incident optical module 40 and the light-emitting optical module 50, to be visualized through the transparent housing body 61. Users can see at least some of the electronic components and their arrangement on the back of the electronic device 1, which helps to improve the technological feel, personalization and overall aesthetics of the electronic device 1.

[0048] In this embodiment, after the housing body 61 is fixedly connected to the middle frame 10, the first surface 611 of the housing body 61 is exposed so that the user can directly view the appearance of the housing body 61, and the first surface 611 of the housing body 61 can present an aesthetic effect, thereby improving the appearance characteristics of the electronic device 1. Moreover, the housing body 61 is made of glass, such as high-alumina-silicon glass or nanocrystalline glass, which has characteristics such as high hardness, wear resistance, and scratch resistance. It is understood that the first surface 611 (i.e., the appearance surface) of the housing body 61 is a relatively smooth surface so that the housing body 61 has better aesthetic characteristics.

[0049] In related technologies, smartphone cameras have a decorative piece (Deco) on the outermost side, and the Deco and the light-in-the-camera side are required to be made of a scratch-resistant, light-transmitting material, such as sapphire glass. Compared with ordinary glass or other transparent materials such as plastics, sapphire glass has good scratch resistance. Therefore, in related technologies, the back cover and Deco of smartphones are designed separately to meet the scratch resistance requirements of the light-in-the-camera side.

[0050] In this embodiment, the housing assembly 60 further includes an effect layer corresponding to the optical module. For example, the effect layer is located in the light-incident direction of the light-incident optical module 40, or in the light-outceasing direction of the light-outceasing optical module 50. The effect layer may include at least one or more of the following: a light-reducing layer, a light-enhancing layer, a light-diffusing layer, and a color layer. The effect layer is used to transmit light through the optical module and form a preset display effect and display brightness.

[0051] like Figure 4 and Figure 5 As shown, in an exemplary embodiment, the light-transmitting area 613 may include a first light-transmitting area 6131 and a second light-transmitting area 6132. The first light-transmitting area 6131 corresponds to the position of the light-emitting optical module 50. The first light-transmitting area 6131 of the housing body 61 can be used as a transparent display cover for the light-emitting optical module 50, improving the overall integrity and aesthetics of the electronic device 1. The light-emitting optical module 50 displays corresponding image information through the first light-transmitting area 6131. ​​For example, the light-emitting optical module 50 lights up or turns off the screen through the first light-transmitting area 6131; or, for example, the light-emitting optical module 50 displays image information of different brightness or different colors through the first light-transmitting area 6131. ​​The position of the second light-transmitting area 6132 corresponds to the position of the light-incident optical module 40, that is, the second light-transmitting area 6132 of the housing body 61 can be used as a transparent cover for the light-incident optical module 40, thereby improving the overall integrity and aesthetics of the electronic device 1.

[0052] In this embodiment, the orthographic projection of the light-emitting optical module 50 onto the middle frame 10 is located within the range of the orthographic projection of the first light-transmitting region 6131 onto the middle frame 10, that is, the first light-transmitting region 6131 overlaps with the orthographic projection of the light-emitting optical module 50 in the direction of the middle frame 10. The orthographic projection of the light-incident optical module 40 onto the middle frame 10 is located within the range of the orthographic projection of the second light-transmitting region 6132 onto the middle frame 10, that is, the second light-transmitting region 6132 overlaps with the orthographic projection of the light-incident optical module 40 in the direction of the middle frame 10.

[0053] In an exemplary embodiment, the protective layer may include a first protective layer and a second protective layer. Please refer to the following: Figure 6 , Figure 6 This is a schematic diagram of the layer structure of a housing assembly disclosed in an embodiment of this application. The protective layer includes a first protective layer 63 and a second protective layer 64. The size and shape of the first protective layer 63 match the size and shape of the first light-transmitting region 6131. ​​The first protective layer 63 is attached to the first surface 611 of the first light-transmitting region 6131 and corresponds to the position of the light-emitting optical module 50. The size and shape of the second protective layer 64 match the size and shape of the second light-transmitting region 6132. The second protective layer 64 is attached to the first surface 611 of the second light-transmitting region 6132 and corresponds to the position of the light-incident optical module 40.

[0054] In this embodiment, the first protective layer 63 can increase the Mohs hardness of the first light-transmitting area 6131, preventing scratches on the surface of the first light-transmitting area 6131. ​​Therefore, by providing the first protective layer 63 on the housing body 61 at the position corresponding to the first light-transmitting area 6131, the Mohs hardness of the surface of the first light-transmitting area 6131 can be increased, enhancing scratch and abrasion resistance. This improves the image display clarity of the light-emitting optical module 50 corresponding to the first light-transmitting area 6131, thereby enhancing the display effect of the light-emitting optical module 50. For example, the Mohs hardness of the first light-transmitting area 6131 with the first protective layer 63 attached can be 7H (Hard).

[0055] In this embodiment, the second protective layer 64 can increase the Mohs hardness of the second light-transmitting area 6132, preventing scratches on the surface of the second light-transmitting area 6132. Therefore, by providing the second protective layer 64 on the housing body 61 at the position corresponding to the second light-transmitting area 6132, the Mohs hardness of the surface where the second light-transmitting area 6132 is located can be increased, enhancing scratch and abrasion resistance. This improves the light transmittance of the incident optical module 40 corresponding to the second light-transmitting area 6132, thereby improving the imaging effect of the incident optical module 40. For example, the Mohs hardness of the second light-transmitting area 6132 with the second protective layer 64 attached can be 7H.

[0056] In this embodiment, the effect layer includes a light-reducing layer 69, which is attached to the second surface 612 (i.e., the inner surface of the housing body 61) and corresponds to the position of the light-emitting optical module 50. The light-reducing layer 69 is used to reduce or eliminate reflected light from the light-emitting surface of the light-emitting optical module 50 and increase light transmittance and light transmission, thereby reducing or eliminating stray light. In an exemplary embodiment, the light-reducing layer 69 may be an anti-reflective (AR) film, which increases light transmittance and light transmission by reducing surface reflection. Therefore, by performing anti-reflective treatment on the second surface 612 of the housing body 61 corresponding to the position of the light-emitting optical module 50, the light transmittance of the light-emitting optical module 50 can be improved, and the light reflectance can be reduced to achieve the purpose of enhancing light transmission.

[0057] In this embodiment, the light-reducing layer 69 can be directly formed on the second surface 612 of the housing body 61 using a vacuum evaporation coating method, and corresponds to the position of the light-emitting optical module 50. Specifically, an anti-reflection coating is formed by performing an anti-reflection coating treatment on the inner surface (i.e., the second surface 612) of the housing body 61 corresponding to the position of the light-emitting optical module 50.

[0058] In an exemplary embodiment, the thickness of the light-reducing layer 69 may be 650nm-750nm, for example, 650nm, 670nm, 680nm, 700nm, 710nm, 730nm, 740nm, 750nm, or other values. This application does not impose specific limitations on this.

[0059] In summary, the housing assembly 60 disclosed in this application is applied to the back side of an electronic device body having a mid-frame 10. The housing assembly 60 includes a housing body 61, at least partially comprising a light-transmitting region 613. The light-transmitting region 613 overlaps at least with the orthographic projection of the optical module of the electronic device 1 in the direction of the mid-frame 10. The optical module includes an emitting optical module 50 and / or an incident optical module 40. The light-transmitting region 613 is used for the transmission of light emitted by the emitting optical module 50, and / or for the transmission of light through the housing body 61, which is then received by the incident optical module 40. The light-transmitting region 613 includes a first surface 611 disposed opposite to the electronic device body and a second surface 612 disposed close to the electronic device body. The first surface 611 is provided with a protective layer, which at least corresponds to the optical module, and the Mohs hardness of the protective layer is greater than that of the housing body 61. Therefore, the housing body 61 of the housing assembly 60 of this application adopts at least a partially transparent design, and by providing a protective layer on the first surface 611 (i.e. the outer surface) of the light-transmitting area corresponding to the optical module, and the Mohs hardness of the protective layer is greater than that of the housing body, the scratch and abrasion resistance of the housing body 61 is improved, thereby solving the problem of the lack of aesthetic appeal and integrity of the back cover of the housing assembly in the related art.

[0060] Furthermore, the housing assembly 60, by providing a corresponding protective layer on the outer surface (i.e., the first surface 611) of the housing body 61 corresponding to the position of the optical module, not only increases the protection of the optical module and improves the overall integrity and aesthetics of the electronic device 1, but also, by thickening the outer side of the housing body 61 or by providing a certain curvature on the outer surface of the housing body 61, the housing body 61 itself can have general Deco functions. Therefore, the housing assembly 60 does not require a decorative ring (CAM Deco) design, making the structure of the housing body 61 simpler, the appearance more minimalist, and the overall appearance more integrated, further improving the overall appearance of the electronic device 1.

[0061] Furthermore, compared to the light-emitting optical module in related technologies, which requires an additional lamp cover to reduce the brightness of the LED beads, the housing assembly 60 in this application embodiment can reduce the brightness of the LED beads by coating / frosting the inner surface (i.e., the second surface 612) of the housing body 61 and designing it as an integral back cover with a light-reducing effect, thereby reducing the manufacturing cost.

[0062] In the embodiments of this application, such as Figure 6As shown, the effect layer further includes a brightness enhancement layer 72, which is attached to the second surface 612 (i.e., the inner surface of the housing body 61) of the housing body 61 and corresponds to the position of the incident optical module 40. The brightness enhancement layer 72 is used to reduce the reflection and scattering of light from the incident optical module 40 to achieve a preset brightness, thereby improving luminous efficiency and the brightness of light entering the incident optical module 40. In an exemplary embodiment, the brightness enhancement layer 72 may be a brightness enhancement film.

[0063] In this embodiment, the brightness enhancement layer 72 is mainly based on polycarbonate (PC), polyvinyl alcohol (PVA), or PET (polyester), and prism patterns or micro / nano optical structures are fabricated on its surface using precision molding technology. Alternatively, a double-layer brightness enhancement film composite process can be employed, where a base film and a functional layer with diffusion particles are bonded together using UV resin adhesive to further optimize light efficiency.

[0064] In this embodiment, the effect layer may further include a light-diffusing layer. This light-diffusing layer is attached to the inner surface (i.e., the second surface 612) of the housing body 61 and covers the light-transmitting area 613. Specifically, the light-diffusing layer covers the brightness enhancement layer 72 and the light reduction layer 69, and corresponds to the incident light optical module 40 and the emitted light optical module 50. The light-diffusing layer is used to optimize the light distribution of the incident light optical module 40 and the emitted light optical module 50 to achieve uniform light intensity distribution across the entire area.

[0065] In the embodiments of this application, such as Figure 6 As shown, the effect layer also includes a color layer 65, which is attached to the second surface 612 (i.e., the inner surface of the housing body 61) and covers the light-reducing layer 69 and the light-diffusing layer. The color layer 65 is used to adjust the color and brightness of the image displayed by the light-emitting optical module 50. Therefore, the color layer 65 is color-adjustable. By attaching the color layer 65 to the second surface 612 (i.e., the inner surface) of the housing body 61 and positioning the color layer 65 corresponding to the light-emitting optical module 50, the color and brightness of the image displayed by the light-emitting optical module 50 can be adjusted, allowing the light-emitting optical module 50 to display a preset image color and brightness. Moreover, by setting the color layer 65 to adjust the screen brightness and color of the light-emitting optical module 50, the light-emitting optical module 50 does not need to have a dot matrix screen cover added to the housing body 61, making the product structure simpler and the appearance more minimalist, further improving the overall appearance, aesthetics, and display effect of the electronic device 1.

[0066] It is understood that by attaching the color layer 65 to the inner surface of the housing body 61, impacts can be effectively buffered to prevent the screen from cracking, or to prevent the glass back cover from shattering and scattering due to accidental impacts to the electronic device 1, reducing hidden damage to the glass back cover, and maintaining the unique gloss and texture of the reinforced glass back cover while improving surface hardness. The structure of the color layer 65 may sequentially include: a protective film, a hardening layer, a transparent polyester film, an adhesive layer, and a release film.

[0067] In this embodiment, the effect layer may include at least one or more of the following: a light-reducing layer, a light-enhancing layer, a light-diffusing layer, and a color layer. The effect layer is used to transmit light through the optical module and form a preset display effect. Specifically, the light-emitting optical module 50 may be composed of multiple light-emitting chips, and the light-reducing layer 69 is used to reduce the brightness transmitted through the housing assembly when the light-emitting optical module 50 is in operation; and / or, the light-incident optical module 40 may be composed of multiple cameras, and the light-enhancing layer 72 is used to reduce light reflection and scattering when the light-incident optical module 40 is in operation to achieve a preset brightness; and / or, the light-emitting optical module 50 may be composed of multiple light-emitting chips, and the light-diffusing layer is used to ensure uniform display of light transmitted through the housing assembly when the light-emitting optical module 50 is in operation; and / or, the light-emitting optical module 50 may be composed of multiple light-emitting chips, and the color layer 65 is used to adjust the color of light transmitted through the housing assembly 60 when the light-emitting optical module 50 is in operation.

[0068] It is understood that, in this embodiment, the effect layer is disposed on the second surface 612 (i.e., the inner surface of the housing body 61) and corresponds to the area where the protective layer is disposed on the first surface 611. The effect layer is used to transmit light through the optical module and form a preset display effect and display brightness. For example, the effect layer can be used to reduce the brightness transmitted through the housing assembly 60 when the light-emitting optical module 50 is in working state; and / or, to reduce the reflection and scattering of light when the light-incident optical module 40 is in working state to achieve a preset brightness; and / or, to make the light transmitted through the housing assembly 60 when the light-emitting optical module 50 is in working state uniformly displayed; and / or, to adjust the color of the light transmitted through the housing assembly 60 when the light-emitting optical module 50 is in working state.

[0069] In this embodiment, the housing assembly 60 may further include an adhesive layer disposed between the color layer 65 and the inner surface (i.e., the second surface 612) of the housing body 61. The color layer 65 is adhered and fixed to the housing body 61 by the adhesive layer. The adhesive layer may be an optical adhesive layer, a regular adhesive layer, or a double-sided adhesive layer. The adhesive layer reliably fixes the color layer 65 to the inner surface of the housing body 61 and also provides cushioning and shock absorption in the event of an accidental drop of the electronic device 1. Furthermore, the circumferential adhesion and fixation of the housing body 61 to the adhesive layer improves the sealing performance between the housing body 61 and the color layer 65, thereby enhancing the waterproof and dustproof performance of the electronic device 1.

[0070] It is understood that the effect layer, including the light-reducing layer 69, the light-enhancing layer 72, the light-diffusing layer, and the color layer 65, can be implemented as described above. Figure 6 The order shown can also be arranged in other orders according to actual needs or process design. It is also understood that the light-reducing layer 69, the light-enhancing layer 72, the light-diffusing layer, and the color layer 65 included in the effect layer can be reduced or reduced as needed, or other functional film layers can be added according to actual needs. This application does not make specific limitations in this regard.

[0071] In this embodiment, the housing assembly 60 further includes a color layer 65 corresponding to the light-emitting optical module 50. The color layer 65 includes multiple sub-color layers of different colors, each of which corresponds to a different region of the light-emitting optical module 50. The multiple sub-color layers are used to change the color of the light transmitted through the housing assembly 60 by the light-emitting optical module 50.

[0072] In this embodiment, the housing assembly 60 further includes at least one opaque first decorative layer. The first decorative layer is disposed on the second surface 612 and overlaps with the orthographic projection of at least one electronic component of the electronic device 1 in the direction of the middle frame 10, thereby covering the electronic component. Therefore, by providing an opaque first decorative layer on the second surface 612 of the housing body 61, and ensuring that the orthographic projection of the first decorative layer in the direction of the middle frame 10 overlaps with the orthographic projection of the electronic component of the electronic device 1 in the direction of the middle frame 10, the first decorative layer can conceal the corresponding electronic component while allowing it to be visualized through the transparent housing body. This enhances the appearance and overall aesthetics of the electronic device 1.

[0073] In another embodiment of this application, the housing assembly 60 may further include at least one second decorative layer with a surface texture, the second decorative layer being attached to the second surface 612, the surface texture corresponding to a functional component of the electronic device 1. The functional components include, but are not limited to, sensors, ribbon cables, motherboards, coils, etc., and this embodiment of the application does not limit the specific components.

[0074] For example, the housing assembly 60 includes two second decorative layers with surface textures. Correspondingly, two decorative regions, namely a first decorative region 615 and a second decorative region 616, are formed on the second surface 612 of the housing assembly 60. The first decorative region 615 is formed by one of the second decorative layers, and the second decorative region 616 is formed by another second decorative layer, such that the first decorative region 615 and the second decorative region 616 have the same or different texture patterns. It is understood that the first decorative region 615 and the second decorative region 616 can be arranged adjacently, spaced apart, or spliced ​​together to form different patterns. The first decorative region 615 and the second decorative region 616 can have the same texture pattern or different texture patterns. For example, the first decorative region 615 and / or the second decorative region 616 can form a texture pattern, or a texture pattern can be formed by glazing or other methods, thereby obtaining a better appearance effect and improving the appearance characteristics of the electronic device 1.

[0075] In an exemplary embodiment, the positions of the first decorative area 615 and the second decorative layer correspond to the positions of the coils in the electronic device 1. To enhance the sense of layering and aesthetics of the electronic device 1, the shape of the first decorative area 615 can be set to match the shape of the coils. Correspondingly, the texture pattern and color on the first decorative area 615 also match the winding method and color of the coils. It is understood that the positions of the second decorative area 616 and another second decorative layer can also be set to correspond to the positions of the coils in the electronic device 1.

[0076] In this embodiment, by designing the surface texture and color of the second decorative layer, the transparent shell body can present a variety of visual effects. Specifically, ultraviolet texture transfer technology can be used to design the texture of the second decorative layer. This involves using liquid UV adhesive to cure under ultraviolet light to replicate fine texture structures, thereby creating effects including brushed texture, sunburst texture, sandblasted texture, 3D surface, leather texture, iridescent effect, bumpy effect, matte finish, glossy finish, and high-gloss finish. The color can be monochrome or gradient; this application does not specifically limit this.

[0077] In this embodiment, the protective layer may be a sapphire lens. The first surface 611 of the housing body 61 has a recessed groove in the direction of the second surface 612. The position of the groove corresponds to the position of the light-incident optical module 40. The size and shape of the groove match the size and shape of the sapphire lens. The sapphire lens is embedded in the groove, and the outer surface of the sapphire lens is flush with the first surface 611. That is, the thickness of the sapphire lens is approximately equal to the depth of the groove.

[0078] Please refer to the following: Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of the structure of a housing assembly disclosed in an embodiment of this application. Figure 8 for Figure 7 The diagram shows the structural fit between the protective layer and the housing body. In this embodiment, the second protective layer 64 can be a sapphire lens. The first surface 611 of the housing body 61 has a recessed groove 618 in the direction towards the second surface 612. The position of the groove 618 corresponds to the position of the light-incident optical module 40. The size and shape of the groove match the size and shape of the sapphire lens. The sapphire lens is embedded in the groove 618, and the outer surface of the sapphire lens is flush with the first surface 611, that is, the thickness of the sapphire lens is approximately equal to the depth of the groove 618.

[0079] Understandably, a sapphire lens is used as a protective layer because it has high light transmittance to facilitate light entry into the light-receiving optical module 40. The sapphire lens can be circular, rectangular, rounded rectangular, racetrack-shaped, pentagonal, hexagonal, or other shapes. Furthermore, the sapphire lens can have high scratch resistance to prevent the surface of the protective layer from being easily scratched. Of course, the surface of the sapphire lens can also be coated with an optical film or other reinforcing films, which may include one or more of infrared filtering layers, ultraviolet filtering layers, and reinforcing layers.

[0080] In this embodiment, the housing assembly 60 further includes an electrochromic layer 66, which is disposed on the surface of the color layer 65 facing away from the housing body 61. The electrochromic layer 66 is used to adjust the color and / or transparency of the light emitted by the light-emitting optical module 50, thereby improving the visual appearance and aesthetics of the electronic device 1. It is understood that the electrochromic layer 66 can be bonded and fixed to the surface of the color layer 65 facing away from the housing body 61 by any one of optical adhesive layer, adhesive layer, or double-sided adhesive layer. The electrochromic layer 66 may have a reserved second light-transmitting area 6132, that is, the electrochromic layer 66 does not cover the second light-transmitting area 6132. For example, through holes of corresponding shape and size can be opened in the electrochromic layer 66 corresponding to the second light-transmitting area 6132, so that the second light-transmitting area 6132 is exposed by the electrochromic layer 66.

[0081] In this embodiment, the housing assembly 60 may further include an anti-glare layer 67. The anti-glare layer 67 is disposed on the surface of the electrochromic layer 66 opposite to the color layer 65. The anti-glare layer 67 is used to improve the viewing angle of the housing body 61 and the light-emitting optical module 50, reduce the interference of ambient light on the light-receiving optical module 40, and reduce the reflection of the housing body 61. It is understood that the anti-glare layer 67 can be bonded and fixed to the surface of the electrochromic layer 66 opposite to the color layer 65 by any one of optical adhesive layer, adhesive layer, or double-sided adhesive layer.

[0082] In other embodiments of this application, in order to reduce the overall thickness of the housing assembly 60, the electrochromic layer 66 can be omitted, that is, the anti-glare layer 67 is disposed on the surface of the color layer 65 facing away from the housing body 61. Moreover, the anti-glare layer 67 can be bonded and fixed to the surface of the color layer 65 facing away from the housing body 61 by any one of optical adhesive layer, adhesive layer, and double-sided adhesive layer.

[0083] In this embodiment, the housing assembly 60 further includes an anti-fingerprint (AF) layer 68, which is disposed on the first surface 611 of the housing body 61 (i.e., the outer surface of the housing body 61) and covers the first protective layer 63 and the second protective layer 64. The anti-fingerprint layer 68 is used to protect the housing assembly 60 from external environmental corrosion and can also improve the appearance and visual effect of the housing assembly 60. The principle of the anti-fingerprint layer is to disperse the fingerprint texture, making the fingerprint on the housing assembly invisible, thus playing a certain antibacterial role. After the anti-fingerprint coating treatment, the surface of the object will exhibit good hydrophobicity and oleophobicity. Therefore, the anti-fingerprint film can also reduce the adhesion of various stains, is waterproof and oil-proof, and the already adhered stains can be easily removed. Because it is a highly adhesive film layer, it can continue to function after wiping with a thin gauze, etc. At the same time, the film layer will not peel off, so the appearance will not deteriorate. It is understood that the anti-fingerprint layer 68 can be bonded and fixed to the first surface 611 (i.e. the outer surface of the housing body 61) of the housing body 61 by any one of optical adhesive layer, adhesive layer, or double-sided adhesive layer.

[0084] In an exemplary embodiment, the thickness of the anti-fingerprint layer 68 is 80nm-120nm, for example, 80nm, 82nm, 85nm, 88nm, 90nm, 95nm, 98nm, 100nm, 105nm, 108nm, 110nm, 115nm, 118nm, 120nm, or other values. This application does not impose specific limitations on this.

[0085] In this embodiment, the housing body 61 of the electronic device 1 is hardened primarily through chemical strengthening (mainly ion exchange) to improve its hardness, impact resistance, and scratch resistance. For example, ion exchange technology replaces small ions (Na+) on the glass surface with large ions (K+), creating surface compressive stress and improving the glass's hardness and impact resistance. A commonly used solution is molten KNO3 (potassium nitrate). Method 1: Single-layer ion exchange (ordinary chemical strengthening), specifically, the glass is immersed in molten KNO3 at temperatures above 400°C, where surface Na+ is replaced by K+, forming a compressive stress layer 50-100 μm deep, thus improving hardness and impact resistance. Method 2: Double-layer ion exchange (deep strengthening, enhancing durability), specifically, initial exchange with Li+ followed by secondary strengthening with K+ forms a deeper strengthening layer, improving durability. Therefore, the shell after chemical strengthening and hardening treatment has the following advantages: high hardness (more scratch-resistant than ordinary tempered glass (Mohs hardness can reach 6-7)); it can also strengthen thin glass, making it suitable for ultra-thin screen glass; it has better optical performance, high light transmittance, and no optical distortion of ordinary tempered glass; and it is not easy to break into particles after breakage.

[0086] It is understood that in other embodiments of this application, the housing assembly 60 may also include other optical films or other films with enhanced properties. The optical films may include one or more of the following: an infrared filter layer, an ultraviolet filter layer, an anti-reflective film, a reinforcing layer, and a privacy film.

[0087] Based on the same technical concept, embodiments of this application also provide an electronic device. Please refer to... Figure 1 and Figure 2 The electronic device 1 provided in this application embodiment includes a mid-frame 10, a main display module 20, a circuit board 30, an optical module, and the aforementioned housing assembly 60. The optical module includes an incident light optical module 40 and an exiting light optical module 50, wherein the incident light optical module 40 may be a camera module, and the exiting light optical module 50 may be a rear display assembly. Because... Figure 1 and Figure 2 The illustrated embodiment has provided a relatively detailed description of the mid-frame 10, main display module 20, circuit board 30, light-incident optical module 40, and light-exit optical module 50, and Figures 3 to 5 The illustrated embodiments have already described the housing assembly 60 in detail, and will not be repeated here. Therefore, the electronic device 1 provided in this application has the technical effects of the technical solutions in any of the above embodiments, and the explanations of the same or corresponding structures and terms as in the above embodiments will not be repeated here.

[0088] In this embodiment, the optical module includes a rear display panel assembly, which may be composed of an array of LED beads. The housing assembly 60 further includes an effect layer, corresponding to the rear display panel assembly. The effect layer is used to transmit light through the rear display panel assembly and form a preset display effect. For example, the effect layer can be used to reduce the brightness transmitted through the housing assembly 60 when the rear display panel assembly is in operation; and / or, to make the light transmitted through the housing assembly 60 when the rear display panel assembly is in operation uniformly displayed; and / or, to adjust the color of the light transmitted through the housing assembly 60 when the rear display panel assembly is in operation.

[0089] In this embodiment, the light-incident optical module 40 is fixed to the middle frame 10 and electrically connected to the circuit board 30. The light-incident optical module 40 is positioned near the frame 11 of the electronic device 1, that is, the edge of the light-incident optical module 40 is tangent to the stepped surface of the middle frame 10, so that the center of the camera of the light-incident optical module 40 is used as a positioning reference point, thereby facilitating the alignment of the camera of the light-incident optical module 40 with the second light-transmitting area 6132.

[0090] In this embodiment, the incident light optical module 40 includes a first camera 41, a second camera 42, and a third camera 43, which are used for taking pictures and videos. The first camera 41 may be a periscope camera, and the second camera 42 and the third camera 43 may be any two different types of cameras selected from conventional cameras, wide-angle cameras, ultra-wide-angle cameras, telephoto cameras, monochrome cameras, and depth cameras.

[0091] In this embodiment, all four corners of the first camera 41 can be designed with rounded arcs, which makes it aesthetically pleasing and increases the overall visual appeal of the housing assembly 60.

[0092] In this embodiment, the first camera 41 is located inside the housing assembly 60 and adjacent to the second surface 612 of the housing body 61. The position of the first camera 41 corresponds to that of the protective layer. The Mohs hardness of the protective layer is greater than that of the housing body 61. Therefore, it can improve the scratch and abrasion resistance of the outer surface of the housing body 61 corresponding to the first camera 41, thereby avoiding the problem of low light transmittance due to scratches or abrasions.

[0093] At least one of the second camera 42 and the third camera 43 protrudes from the housing assembly 60. That is, at least one of the second camera 42 and the third camera 43 is exposed through the anti-glare layer 67, the electrochromic layer 66, the color layer 65, the housing body 61, and the anti-fingerprint layer 68. Therefore, at least one of the second camera 42 and the third camera 43 protrudes from the surface of the anti-fingerprint layer 68 facing away from the housing body 61. Based on this, when the housing assembly 60 of the electronic device 1 is placed on a support such as a desktop, the first camera 41 and a portion of the housing assembly 60 are suspended in mid-air, thus reducing friction and scratches from the desktop or other support on the suspended surface of the housing assembly 60.

[0094] It is understood that the light-incident optical module 40 may also include an image sensor, a filter, an image signal processor, a flash, focusing and optical image stabilization elements, and other auxiliary components to increase the imaging quality of the light-incident optical module 40.

[0095] In this embodiment, the electronic device 1 further includes at least one pressure-sensitive button 70, which is disposed near the edge of the first surface 611 of the housing body 61. The housing body 61 includes a first decorative layer attached to the second surface 612, and the orthographic projection of the first decorative layer in the direction of the mid-frame 10 of the electronic device 1 overlaps with the sensor body of the pressure-sensitive button 70. The pressure-sensitive button 70 receives deformation signals transmitted through the first decorative layer by the deformation of the housing body 61 to realize corresponding input operations.

[0096] In this embodiment, the housing body 61 further includes a brightening region 617, which is disposed on the inner surface of the housing body 61 and corresponds to the position of the flash of the light-incident optical module 40. By providing multiple concentric ring-shaped or spiral-shaped patterns within the brightening region 617 of the housing body 61, the light from the flash can be utilized more efficiently, increasing the illumination brightness of the brightening region 617 and thus improving the shooting effect of the light-incident optical module 40.

[0097] Understandably, in some embodiments, the electronic device 1 may have communication capabilities, i.e., it can establish communication with the network via 4G (fourth-generation mobile communication technology), 5G (fifth-generation mobile communication technology), 6G (sixth-generation mobile communication technology), or W-LAN (wireless local area network), or other communication methods that may emerge in the future. For the sake of simplicity, this application embodiment does not further limit this aspect.

[0098] In an exemplary embodiment, the electronic device 1 may further include a processor and a memory. The processor is electrically connected to the main display module 20, the light-incident optical module 40, and the light-emitting optical module 50, and is used to control the main display module 20 and the light-emitting optical module 50 to display content, and to control the light-incident optical module 40 to take pictures. The memory is electrically connected to the processor, and is used to store the program code required for the processor to run, and to control the display content of the main display module 20 and the light-emitting optical module 50, etc.

[0099] In an exemplary embodiment, the memory may include volatile memory, such as random access memory (RAM); the memory may also include non-volatile memory (NVM), such as read-only memory (ROM), flash memory (FM), hard disk drive (HDD), or solid-state drive (SSD). The memory may also include combinations of the above types of memory.

[0100] In an exemplary embodiment, the processor includes one or more general-purpose processors, wherein the general-purpose processor can be any type of device capable of processing electronic instructions, including a central processing unit (CPU), microprocessor, microcontroller, main processor, and controller, etc. The processor is used to execute various types of digital storage instructions, such as software or firmware programs stored in the memory, which enable the computing device to provide a wide range of services.

[0101] In summary, the electronic device 1 provided in this application embodiment includes an optical module and a housing assembly 60. The housing assembly 60 includes a housing body 61, at least partially comprising a light-transmitting region 613. The light-transmitting region 613 overlaps at least with the orthographic projection of the optical module of the electronic device 1 in the direction of the mid-frame 10. The optical module includes an emitting optical module 50 and / or an incident optical module 40. The light-transmitting region 613 is used for the transmission of light emitted by the emitting optical module 50 and / or for the transmission of light through the housing body 61, which is then received by the incident optical module 40. The light-transmitting region 613 includes a first surface 611 disposed opposite to the electronic device body and a second surface 612 disposed close to the electronic device body. The first surface 611 is provided with a protective layer, which corresponds at least to the optical module, and the Mohs hardness of the protective layer is greater than that of the housing body 61. Therefore, the housing body 61 of the housing assembly 60 of this application adopts at least a partially transparent design, and by providing a protective layer on the first surface 611 of the light-transmitting area corresponding to the optical module, and the Mohs hardness of the protective layer is greater than that of the housing body, the scratch and abrasion resistance of the housing body 61 is improved, thus solving the problem of the lack of aesthetic appeal and integrity of the back cover of the housing assembly in the related art.

[0102] Furthermore, the housing assembly 60, by providing a corresponding protective layer on the outer surface (i.e., the first surface 611) of the housing body 61 corresponding to the position of the optical module, not only increases the protection of the optical module and improves the overall integrity and aesthetics of the electronic device 1, but also, by thickening the outer side of the housing body 61 or by providing a certain curvature on the outer surface of the housing body 61, the housing body 61 can have general Deco functionality. Therefore, the housing assembly 60 does not require a decorative ring (CAM Deco) design, making the structure of the housing body 61 simpler, the appearance more minimalist, and the overall appearance more consistent, further improving the overall appearance of the electronic device 1.

[0103] Furthermore, by attaching the color layer 65 to the inner surface of the housing body 61, and ensuring that the color layer 65 corresponds to the position of the light-emitting optical module 50, the color and brightness of the image displayed by the light-emitting optical module 50 can be adjusted, allowing the light-emitting optical module 50 to display preset image colors and brightness. Moreover, by adjusting the screen brightness and color of the light-emitting optical module 50 using the color layer 65, the light-emitting optical module 50 does not require an additional dot-matrix screen cover on the housing body 61, resulting in a simpler product structure and a more minimalist appearance, further improving the overall appearance, aesthetics, and display effect of the electronic device 1.

[0104] In addition, compared to the light-emitting optical module in related technologies, which requires an additional lamp cover to reduce the brightness of the LEDs, the housing assembly 60 in this application embodiment can reduce the brightness of the LEDs by coating / frosting the inner surface (i.e., the second surface 612) of the housing body 61 and designing it as an integral back cover with a light-reducing effect, thereby reducing the manufacturing cost.
